Apparatus for disposing of a used thermal stencil master sheet and a process for disposing of the same

Abstract

An apparatus for disposing of a used thermal stencil master sheet, in a superior disposing efficiency and secret-retainability, and a process for disposing of the same are provided, which apparatus is provided with a stripping nail for stripping a used thermal stencil master sheet wound up on a stencil body therefrom, a waste stencil box for encasing the stripped master sheet and rolls for waste stencil for feeding the master sheet into the box, and is characterized by providing a means for heating the master sheet so that it is heat-shrinked and/or melted within the box, and which process comprises discarding the used master sheet of a thermal stencil master sheet, and heating the used master sheet so as to subject it to heat-shrinkage and/or melting.

What we claim is: 
     
       1. An apparatus for disposing of a used thermal stencil master sheet, which comprises a stripping means for stripping a used thermal stencil master sheet wound up on a stencil body, a box for encasing the stripped master sheet, a feed means for feeding said master sheet to the inside of said box, and a heating means for heating said master sheet so that it is shrunk and/or molten within said box. 
     
     
       2. An apparatus for disposing of a used thermal stencil master sheet according to claim 1, said feed means is a pair of feed rolls provided at an opening of said box, said stripping means is a nail journaled to the axis of one of rolls, and said heating means is a heater provided at at least one of said feed rolls. 
     
     
       3. An apparatus for disposing of a used thermal stencil master sheet according to claim 1, wherein said heating means is a pair of rolls at least one of which has a heater, provided at the outlet side of said feed rolls. 
     
     
       4. An apparatus for disposing of a used thermal stencil master sheet according to claim 1, wherein said heating means comprises an infrared lamp and a reflection plate thereof which are provided below a guide means for guiding said thermal stencil sheet delivered from said feed rolls so as to pass in front of the infrared lamp.
